Julie wrote the rate $108 in 6 weeks as a unit rate. Determine her mistake and correct it.

Sagot :

Unit rate is per unit; therefore, to determine the rate for one week you must divide each part if the problem by 6, giving you the unit rate which is $18.00 per week.

we know that

A unit rate is a ratio between two different units with a denominator of one

so

the rate [tex] \$108 [/tex] in [tex] 6 [/tex] weeks is not a unit rate

To find the unit rate divide [tex] \$108 [/tex] by [tex] 6\ weeks [/tex]

[tex] \frac{108}{6} = 18\ \frac{dollars}{week} [/tex]

therefore

the answer is

The unit rate is [tex] 18\ \frac{dollars}{week} [/tex]
